Lenovo ThinkPad T550 Power Adapter
When choosing a new charger, the actual Lenovo brand is the best one to choose. If you decide to buy an non-Lenovo adapter, please check on both the volts and amps outputs. Due to the fact that one Lenovo adapter is most likely used on other laptop models, be sure you choose the right one. A universal power adapter can be used if yours is unavailable or backordered. The Lenovo ThinkPad T550 power adapter provides two functions, to charge the onboard battery and powering the laptop.
What happens when my AC adapter really needs to be replaced?
- The laptop does not run using just the AC power adapter
- The majority of Lenovo power chargers will get warm to the touch when they are plugged in for a period of time
- Battery does not charge all the time
